Strong isospin symmetry breaking in light scalar meson production

N. N. Achasov, G. N. Shestakov

Isospin symmetry breaking is discussed as a tool for studying the nature and production mechanisms of light scalar mesons. We are concerned with isospin breaking effects with an am…

To the nature of $χ_{c 2} (2 P)$

N. N. Achasov, Xian-Wei Kang

We expect that $B R (χ_{c 2} (2 P) \to g l u o n g l u o n) ≳ 2%$ if Particle Data Group as well as BaBar and Belle collaboration correctly identified the state. In reality, this branch…

Analysis of the nature of the $ϕ \to γ π η$ and $ϕ \to γ π^{0} π^{0}$ decays

N. N. Achasov, V. V. Gubin

hep-ph/0104081 was put by accident insdead of "replace hep-ph/0101024"(v2). We apologize very much.

Analysis of the nature of the $ϕ \to γ π η$ and $ϕ \to γ π^{0} π^{0}$ decays

N. N. Achasov, V. V. Gubin

We study interference patterns in the $ϕ \to (γ a_{0} + π^{0} ρ) \to γ π η$ and $ϕ \to (γ f_{0} + π^{0} ρ) \to γ π^{0} π^{0}$ reactions. Taking into account the interference, we fit the experimental data and show…

On the Nature of the Scalar a_0(980) and f_0(980)-Mesons

N. N. Achasov

It is presented a critical consideration of all unusual properties of the scalar $a_{0} (980)$ and $f_{0} (980)$ -mesons in the four-quark, two-quark and molecular models. The arguments a…

Search for the scalar $a_{0}$ and $f_{0}$ mesons in the reactions $e^{+} e^{-} \to γ π^{0} π^{0} (η)$

N. N. Achasov, V. V. Gubin

It is shown that the reactions $e^{+} e^{-} \to γ π^{0} π^{0} (η)$ give a good chance for observing scalar $a_{0}$ and $f_{0}$ mesons. In the photon energy region less then 100 MeV the vector meson…
